Thot is to soy, the streiehtedge is designed to hnve twoline indiceting edges, the lower educ normelly lying immedietely abovethe lost completedline on the peper sheet, end the 11p upper edee beinebrought when the streicht edye is in lowered position opposite e line onthe pieten immediately below the heures of u line which hes M6611 rtm11jr WEL l lln Flu. i en upper completed line of tebuloted 2o heures isrepresented et it, end en incompleted line of tobuloted-hgures et it.Alignment of the lost completed line with relation to the straight edgens indicated in Fig. l, will therefore, bring the paper into positionfor printing upon the nentes `lower line. nieuwe however, that epurtielly completed line it is to receive edditionel entries thereon,such partially printed line may be very nccurntely brought to theprinting line by coinpnrison with the upper fece of streightedge lli,.3o in the maenner shown in Fie. 2. This moy be secured by pulling downthe strniehtedee efter the peper hos been inserted., roller it movingidly in the slot of lever il during this ndjustment. the peper beinethus eligned in the position in 35 which it is to be printed, thnt is tosoy, no subsequent line spncine beine necessery, e very nccuintealignment moy be mode..

The member ld hes been termed o streightedee, becouse of its utility inconnection with line dndlo ine. independently oi this function, however,member lll is useful es n peper guide, serving to hold the upper portionof the peper sheet towerd the reor, end owing to its pivotal cherncterend movement towerd the guide lil providlo ine for proper feeding of thepeper. Thot is to soy thnt during the feeding of the peper, the deviceis positioned es e port of the peper guide, while during the printingoperation the device holds the upper edge of the peper reerwnrdiy, 5@without extending nt eny point ecross the printchine.

The invention consists in the novel construction ond combination ofports, es set forth in the appended claims.

Fig. 3 is a right .end elevation of the pieten ond essociuted ports.these ports beine in the positions corresponding to those of' Fig. l.

Fin. 4 is e. similar view, the parts being shown in positionscorresponding to Fig. 2.

in these drawings, the numeral l designotes n cylindrical platen, thejournals t of which ere supported in the framing of o shiftable t; f in`the usuel manner. Platen l may be rotut by the usual knob secured to thejournals t, or by means of e compound lever 3, fulcrumed et t, upon e,sub-freine 'l of the carriage end bovine n tooth t in its upper portionadapted to be enpnped with the teeth il of n peer mounted upon the studend meshing with e pinion d secured upon the pieten.

3.-In a paper feed device, the combination with a cylindrical platen andan adjacent paper guide, of a strip metal straightedge extending alongthe face of and pivoted eccentrically of the axis of said platen, andmeans operable to rotate said platen and to rock said straightedge in adirection opposite to such rotation, adapted to move an edge of saidstraightedge in a substantially tangential path with relation to andaway from said platen and into proximity to said paper guide to form acontinuation thereof.

4. In a paper feed device, the combination with a cylindrical platen andan adjacent paper guide located below the printing line, of a pivotallymounted strip metal straightedge normally extending along the face ofthe platen above the printing line, and means operable to rotate saidplaten and to rock said straightedge in a direction opposite to suchrotation and into proximity to said paper guide to form a continuationthereof.
